25 Claims.

This invention relates to splitting machines and is herein illustrated as embodied in a machine particularly adapted to remove a thin split or skiving from the grain side of a piece of leathl; er such as an insole.

Machines of this type commonly comprise a knife, an internally yieldable roll, for example a rubber roll, and a work support or table having an unyielding gaging edge or corner against l v which the work is progressively pressed by the roll as the work is fed to the knife. The skiving which is removed is usually very thin; and to ensure the removal of such a thin continuous skiving of uniform thickness it is desirable that z the gaging edge or corner be parallel to and below the axis of the roll, parallel to and a certain distance in front of the edge of the knife and at a certain level below said edge, the distance of said edge below the level of the edge of the knife determining the thickness of the skiving which will be removed from the work.

According to one feature of the invention the member which carries this unyielding gaging edge is mounted for adjustment bodily in two directions and for angular adjustment about two axes which are at an angle to each other. In the illustrated embodiment this member is the work support or table; and any one of the four adjustments may be made independently of the three others by manipulating a selected one of four knobs or hand holds.

The knife is adjustable bodily and angularly as is usual in such machines; and to facilitate the proper adjustments of the knife and the member which carries the unyielding gaging edge, there are provided, in accordance with another feature of the invention, indicating. mechanisms which indicate when the proper adjustments have been 0 made. In the illustrated machine there are two pairs of pointer-and-scale mechanisms, one pair for the knife and the other for the work support or table which carries the gaging edge.

Machines of this general type are used very commonly in the shoe industry to remove thin grain skivings from insoles; and it is desirable, in those cases in which the practice at the factory permits it, to provide means for feeding insoles or other pieces of work rapidly to the roll and a knife. To this end there is provided, in

' accordance with another feature of the invention, means for supporting a stack of pieces upon a run of a belt and means for operating the belt to feed the pieces one at a time from the bottom of the stack to the knife and roll; and preferably a receiving receptacle is provided in which the finished pieces are received and stacked.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied 5 in an illustrated machine and pointed out in the appended claims.

Referring to the accompanying drawings:

Fig, 3 is a longitudinal section on the line IIIIII of Fig. 2;

Fig. 4 is a view, partly in section and partly in elevation, of the right-hand end of the machine as viewed in Figs. 1 and 3, the magazine and the parts associated with it having been removed;

Fig. 5 is a view, partly in plan and partly in section, of a portion of the machine, the feed magazine and the feed roll having been omitted, and part of the table having been broken away; and

Fig. 6 is a section on the line VI-VI of Fig. 5.

Referring first to Fig. 3, the general operation of the machine will be described before taking 25 up the details of its construction. The pieces of work, herein shown as insoles, are fed grain side down one by one from a magazine over a fiat table 9, the forward operative end of which consists of a hardened block I I, to a stationary knife [3 and a rubber covered roll I! which cooperate with the unyielding gaging edge formed by the forward corner or edge of the hardened block to remove from the lower face of the work a thin skiving 200. The skivings pass down a 5 chute l9; and the insoles, from which the thin grain skivings have been removed, are carried into a receptacle and stacked. The rubber roll, the knife and the hardened block, which forms the operative forward end of the table 9, act as do the corresponding elements of the machine disclosed in United States Letters Patent No. 1,260,436, granted March 26, 1918, upon an application filed in the name of Thomas J. OKeeffe, the height of the edge of the knife above the adjacent edge or corner of the hardened block determining the thickness of the skiving which is removed and the rubber roll yielding to inequalities in the thickness of the work.

It is desirable that the skivings removed from the work should be as thin as possible, for example of the order of from .002 to .003 of an inch, so as not to waste any considerable amount of stock, and that they should be continuous so as to leave clean, unbroken surfaces on the skived work. 55

axis of the pivot screw 23.

Means is therefore provided for adjusting the parts of the machine so that the operative edge or corner of the hardened block shall be directly below and parallel to the axis of the rubber roll and so that the edge of the knife l3 and the adjacent operative corner of the hardened block H shall be in exact parallel relation and distant from each other both horizontally and vertically by the proper amounts. The table or work support 9 (Fig. 1) has four legs, one approximately at each corner, having fiat lower ends which rest upon flat surfaces formed on a support 21 so that the table may be adjusted forward and back as well as angularly. In order to effect such adjustment the table is mounted for horizontal sliding movement toward and from the knife upon a block 2| which is pivoted about a vertical axis. Referring to Fig. 4, the table 9 has an undercut guideway in which the opposite upwardly flaring edges of the block 2! are received. The block is held stationary, except while the table is being adjusted (at which time, as will presently appear, it may be swung angularly) by a screw 23 the flat head of which is received. in a recess in the upper side of the block and is fastened to the block by a small screw 25. The stem of the screw 23 passes down through a bore in the support 2? (Fig. 3) and has threaded on its lower end a nut 29 through which passes a small bar 3! by which the nut may be turned. When the nut is tight the table 9 is held rigid with and locked to the block 2| and the support 2 When the nut is loose the table may slide on the block, and both the table and the block may be swung together about the Referring to Fig. 5, the table 9 is urged at all times to move toward the knife 13 by two compression springs 33, 35, one end of each spring being located in a socket in the block 2| and the other end engaging a downwardly extending lug (Fig. 3) on the forward end of the table. Referring again to Fig. 5, the tendency of the springs to move the table 9 toward the knife is opposed by two cams in the form of wedges 31, 39 which engage with their forward inclined faces stops in the form of vertical rolls El, 43 carried by the support 2!. The opposite flat alined faces of the wedges are in sliding engagement with flat faces formed on a casting 45, said casting being fastened to the table 9 by screws 41 and serving as a support for the feeding magazine which will be described later. The wedge 39 is fastened by a pin 49 to a rod 51 which passes through the wedges, said rod having on its right-hand end, as viewed in Fig. 5, a lefthand thread and on its left-hand end a righthand thread. A coiled compression spring 53, which bears with its right-hand end against a part of the table 9 and with its left-hand end against the bottom of a recess in the wedge 39, urges the wedge and the rod at all times to move toward the left, the location of the wedge and the rod at any time depending upon the position of a knob 55 which is threaded on the right-hand end of the rod and abuts with its left-hand end a boss on the table 9. A second coiled compression spring 5'1, which bears with its right-hand end against the left-hand end of the wedge39 and with its left-hand end against the bottom of a socket in the wedge 3i, urges the wedge 3! at all times to move along the rod 5! toward the left as far as is permitted by a second knob 59 which is threaded on the left-hand end of the rod 5| and abuts the left-hand end of the wedge 37. With this construction, when the nut 29 has been loosened, the table 9 may be adjusted bodily forward and back toward and from the edge of the knife as well as angularly in a horizontal path about a vertical axis of the screw 23. To adjust the table bodily toward the knife the knob 55 is turned right hand on the left-hand thread of the rod as indicated by the arrow. This permits the spring 53 to move the rod and the wedges 31, 39 to the left whereupon the springs 33, 35 move the table 9 bodily toward the knife l3. Turning the knob 55 in the opposite direction moves the wedges 31, 39 to the right and moves the table away from the knife. To swing the table 9 about the axis of the screw 23 so as to aline the operative edge of the table 9 (that is the operative corner of the hardened block II) with the axis of the feed roll, the knob 59 is turned to cause the wedge 31 to be moved along the rod 5| independently of the wedge 39. Turning the knob 59 left-hand on the right-hand thread of the rod, as indicated by the arrow, causes the wedge 31 to be moved to the left by the spring 51 and thereby permits the left-hand end of the operative corner of the hardened block 1 l to be swung toward the knife by the spring 33. Turning the knob 59 in the opposite direction pushes the wedge 31 to the right and swings the left-hand end of the corner of the hardened block ll away from the knife.

The support 27 by which the table 9 is carried in the manner described above is itself mounted for bodily vertical adjustment and for angular adjustment about a horizontal axis, the mounting of the support upon the frame of the machine being similar to the mounting of the table 9 on the support. To this end four bosses, two of which are shown in Fig. 3, have fiat alined vertical faces against which fiat faces on the vertical portion of the support 21 rest. Referring more particularly to Figs. 3 and 4, the downwardly extending vertical portion of the support 21' has formed on that side of it which faces the frame of the machine an undercut guideway I21 in which the opposite edges of a block 6| are slidably received. This block '69 and the support are held stationary, except when the support 27 is being adjusted, by a screw 93 the fiat head of which is received in a recess in the frame 65 of the machine and is fastened to the frame by a small screw 91. The stem of the screw 63 passes through a bore in the block SI and has threaded on its end a nut 69 through which passes a small bar H by which the nut may be turned. When the nut is tight the support 2? is 'held rigid with the block, and both parts are held stationary. When the nut is loose the support may slide on the block, and the table 1 and block may swing in unison about the horizontal axis of the screw 63. The support is urged downward at all times by two compression springs l3, 15, one end of each spring being located in a socket in the block 9i and the other end of each spring resting upon a cross bar 'll fastened by cap screws 79 to the bottom of the support 21. This tendency of the springs to move the support down is resisted by two cams in the form of wedges 8|, 83 which engage with their lower inclined faces stops in the form of horizontally extending rolls 85, 8'! carried by the frame, the upper fiat alined faces of the wedges being in sliding contact with a flat face formed on the support. The wedge 8| is fastened by a pin 89 to a rod 9! which passes through the wedges, said rod having on its right-hand end a right-hand thread and on its left-hand end a left-hand thread. A coiled compression spring 93, which bears with its right-hand end against a part of the support 21 and with its left-hand end against the bottom of a socket in thewedge 8|, urges the wedge and the rod at all times to move to the left, the location of the wedge and the rod at any time depending upon the position of a knob which is threaded on the right-hand end of the rod and abuts a boss on the support 21. A second coiled compression spring 91, which bears with its right-hand end against the wedge BI and with its left-hand end against the bottom of a socket in the wedge 83, urges the wedge 83 at all times to move along the rod to the left (Fig. 4) as far as is permitted by a second knob 99 which is threaded on the left-hand end of the rod, the thread on this end of the rod being a left-hand thread. When the nut 69 is loose, the support 21 may be adjusted bodily up and down as well as angularly in a vertical path about the horizontal axis of the screw 63. To adjust the support 21 bodily up, the knob 95 is turned right hand on the right-hand thread of the rod 9|, as indicated by the arrow. This lifts the support bodily against the force of the springs 13, 15. Turning the knob 95 in the opposite direction permits the springs to lower the support. To swing the support about the axis of the horizontal screw 63, the lefthand knob 99 is turned to cause the wedge 83 to move along the rod 9|. Turning the knob 99 left hand on the left-hand thread, as indicated by the arrow, moves the wedge 83 to the right and raises the left-hand side of the support 21. Turning the knob 99 in the opposite direction permits the spring 13 to lower the left-hand side of the support 21. Thus by turning the four knobs 55, 59 (Fig. 5) and 95, 99, the forward operative edge of the table 9 (Fig. 3), which is constituted by the left-end upper edge or corner of the hardened block II, may be brought into exact parallel relation with the axis of the roll I1 and may be raised and lowered.

It is desirable (Fig. 3) that the operative edge or corner of the hardened block I I be exactly be low and in line with the axis of the rubber roll I1, and that the edge of the knife I3 be parallel to the operative edge of the block and spaced from it horizontally a distance of the order of from .005 to .006 of an inch. The mechanism for adjusting the table 9 has been described. The knife I3 (Fig. 5) is clamped to a part of the frame of the machine which has an inclined flat supporting face, said knife being held in adjusted position by cap screws IOI which pass through slots I03 in the knife and are threaded into the frame. The knife may be adjusted along its support by means of two adjusting screws I05 which are threaded into the frame and have heads which engage the back of the knife. When it is desired to adjust the knife, the cap screws IOI are loosened and one or both of the adjusting screws I05 are turned, depending upon Whether it is desired to adjust the knife angularly or bodily. In order to facilitate the accurate adjustment of the hardened block II and the knife I3 into positions in which the operative corner of the block is below and parallel to the axis of the rubber roll and the edge of the knife is parallel to said corner and properly spaced horizontally from it, a gaging mechanism is provided which indicates by means of pointers and scales when this desired position of parts has been attained.

The gaging mechanism (Figs. 5, 6) comprises a pointer-and-scale mechanism for each end of the hardened block II and a pointer-and-scale mechanism for each end of the knife I 3, there being thus four such mechanisms. Referring to Fig.

5,,the two pointer-and-scale mechanisms forthe knife are indicated as a whole respectively at A and B; and the two pointer-and-scale mechanisms for the hardened block H are indicated as a whole respectively at C and D. Two of the pointer-and-scale mechanisms, A and D, one for the knife and one for the hardened block, are mounted in a bracket I01 having a horizontally extending base which is fastened by screws I09 and a dowel pin III upon the top of one of the stationary bearings II3 (Fig. 4) through which is vertically slidable one of the rods, later to be described, which support the rubber feed roll I1, the base of the bracket I01 having a hole somewhat larger than the diameter of the slide rod. The other two pointer-andscale mechanisms are similarly mounted in a similar bracket II5 (Fig. 5) at the other side of the machine. Since the two pointer-and-scale mechanisms A and D are substantially the same respectively as the two pointer-and-scale mechanisms B and C, only the mechanisms A and D will be described in detail.

Referring more particularly to Fig. 6, the bracket I01, the pointer-and-scale mechanism indicated at D and the pointer-and-scale mechanism indicated at A are shown. The bracket I01 has a horizontal base, as has been described, through which the fastening screws I09 pass. Extending up from this base are two thin walls with a narrow space between them to accommodate the pointers. The inner wall H1 is comparatively low. The outer wall H9 is considerably higher and is forked to provide two upwardly extending arms, on the tops of which are marked scales, the scale I23 (Fig. 5) being for one end of the knife and the scale I2I for one end of the hardened block. Referring again to Fig. 6 the pointer-and-scale mechanism D for one end of the hardened block will be described. The pointer is formed by an outward bend at the upper end of a vertical lever I25 which is pivoted at its lower end about a small pivot I29 carried by the upright walls H1, H9 of the bracket I01. At its lower end the pointer lever I25 has two horizontal extensions one to the right and the other to the left of the pivot I29. To the end of the left-hand extension is attached the lower end of a tension spring I3I the upper end of which is fastened to a pin I32 carried by the wall I I9, said spring tending at all times to swing the pointer lever I25 clockwise about its pivot as far as a set screw I33 will permit. The set screw is threaded through the, right-hand extension of the pointer lever I 25, which is split, and is held in adjusted position by a pinch screw I35. The set screw I33 abuts the horizontal arm of a bell-crank lever I31 which swings about a pivot I39 carried by the walls H1, H9 of the bracket, said bell-crank lever having a short upwardly extending arm carrying a small roll I4I which bears against the front face of the hardened block II at one end thereof (the right-hand end as viewed in Fig. 5). Thus when the righthand end is moved forward and back the pointer moves over the scale I2I. Referring still to Fig. 5, the pointer and scale mechanism 0 at the other end of the hardened block II is substantially like the pointer and scale mechanism D which has just been described; and the pointers are so set, by means of the screws, one of which is shown at I33 in Fig. 6, that when the pointers point to the same numeral on the two scales I2I and I42, the forward edge or corner of the hardened block II is parallel to the axis of the feed roll. The two pointer and scale mechanisms for the hardened block are also set so that when the two pointers point to a selected numeral (the numeral 5 as illustrated) the forward edge of the hardened block is not only parallel to but is also directly below the axis of the feed roll.

After-the hardened block II has been properly located by turning the knobs 55, 59 and observing the two scales I2I, I42, the knife is adjusted toward' or from the block as well as angularly, if necessary, by turning the adjusting screws I05 together or separately to bring the elge of the knife into parallel relation with the forward edge of the corner of the hardened block and to locate the edge of the knife at the proper distance lengthwise of the machine from said corner of the block. To facilitate such adjustment of the knife the two pointer-and-scale mechanisms A and B are provided; and since, as has been stated, these mechanisms are substantially alike, only the mechanism A will be described in detail.

Referring again to- Fig. 6, the pointer for the scale I23 is formed by the upper bent end of a pointer lever I43 pivoted at its lower end about a small pivot I45 carried by the two upright walls II1, II9 of the bracket I91. At the lower end of the pointer lever are two oppositely extending extensions one on each side of the pivot I45. To the end of the right-hand extension is fastened the lower end of a tension spring I41 the upper end of which is fastened to a pin I49 driven into the wall II9, said spring tending at all times to swing. the pointer lever I43 counterclockwise as far as a set screw I5I will permit. This set screw is threaded through the split left-hand extension at the lower end of the pointer lever I43 and isheld in adjusted position by a pinch screw I53. The set screw I5I abuts against one end of a bell-crank lever I which swings about a pivot I51 carried by the upright walls H1, H9 and carries at its upper end a pin I59 the end of which is half-round to form a flat face against which one end (the right-hand end as viewed in Fig. 6) of the edge of the knife abuts. To provide space for this pin and av corresponding one on the opposite side of the machine, as well as to provide space when the hardened block II has been turned over to render another corner of it operative, the hardened block is cut away at its opposite ends, as shown best in Figs. 4 and 5. The pointer-and-scale mechanism B at the other end of the knife is substantially the same as the pointer-and-scale mechanism A. Consequently when the knife is adjusted bodily forward or ..;1 back, the pointers move equally along their respective scales I23, I24; but when the knife is adjusted angularly only one pointer moves. The two pointer and scale mechanisms are so set by means of the set screws, one of which is shown at I5I- in Fig. 6, that when the pointers both point to the same numeral on both scales the knife is parallel to the operative corner of the hardened block II and is spaced from said corner, lengthwise of the machine, a distance which is indicated in thousa-ndths of an inch by the numerals on the scales. As illustrated in Fig. 5, this distance is .005 of an inch. It will be noted (Fig. 6) that the rolls MI, I59 extend out toward the observer and that holes are provided in the plate 1-11 to permit movement of these rolls.

The hardened block II (Fig. 5) is fastened in a recess in the forward end of the table 9 by screws I9I which pass through slots in the block and are threaded into the table. The block may 5 therefore be adjusted and may be turned over widthwise or lengthwise to expose a fresh sharp corner to the knife when desired.

The rubber covered feed and presser roll I1 iscapable of being adjusted vertically as well as angularly and is mounted for yielding movement. To this end (Fig. 4) it is carried by yokes I63, I95 which are fastened respectively by taper pins- I61, I69 to the upper ends of vertical slide rods I1I, I13. The slide rod I1I is slidable in bearings II 3- and I14, and the arms of the yoke I63 carry alined pins I15 (Fig. 6) which extend through the arms of the yoke from the outside and into sockets in a bearing member I11. The other yoke I65 (Fig. 4) has pins, one of which is indicated at I19, which extend into a bearing I8I. The feed roll shaft I82 extends through and is supported by the bearing members I11, I8I and carries the feed roll which consists of a thick rubber cover vulcanized to a metal hub I83, said hub being fastened to, the shaft I82 by a taper pin I85. The slide rod I1I rests with its lower end upon the inclined face of a cam in the form of a wedge block I81, and the slide rod I13 rests similarly upon the inclined face of a second wedge block I89, the slide rods being urged downwardly at all times respectively by coiled compression springs I9I, I93. The spring I9I engages with its upper end the under side of the bearing H3 and rests with its lower end upon a nut I which may be turned to vary the tension of the spring, the nut being threaded upon a sleeve I91 the hub of which is fastened to the slide rod by a taper pin I99. A check nut 20I is provided for locking the nut I95 in adjusted position. The spring I93 on the slide rod I13 is mounted in the same manner as is the spring I9I on the slide rod Hi, there being an adjusting nut 203 to adjust the tension of the spring I93. The two slide rods are thus urged downward at all times by springs the tension of which may be varied. The wedge block I 81, which like the other wedge block I89 is slidable in a borein the frame of the machine, is pinned at 281 to a rod 209 which has a right-hand thread at its right-hand end and a left-hand thread at its left-hand end. The wedge block I89 is slidable on the rod, being urged continually to the left by a coiled compression spring 2 I 9 the right-hand end of which engages a collar 2 fastened to the rod, the position of the block on the rod being determined by a knob 2I3 which is threaded on the left-hand end of the rod and engages the left-hand end of the wedge block. On the right-hand end of the rod is threaded a second knob 2I5 which is held from. longitudinal movement by a thin plate 2I1 fastened to the r frame of the machine and extending into a transverse groove in the knob. Turning the knob 2I5 right hand on its right-hand thread, as indicated in Fig. 4, pulls both wedge blocks I81, I89 to the right and raises the feed roll bodily. Turning the knob 2I5 in the opposite direction permits the springs I9 I, I93 to lower the feed roll bodily. Turning the knob 2I3 left hand on its left-hand thread, as indicated in Fig. 4, pushes the wedge block I89 to the right and raises the left-hand end of the feed roll. Turning the knob 2I3 in the opposite direction permits the spring 2 I 0 to move the wedge block I89 to the left whereupon the spring I93 lowers the left-hand end of the feed roll.

Referring to Figs. 1, 2 and 3 the insoles are fed one by one over the table 9 to the knife and the. combined feed and presser roll, as has been explained above. The stack of insoles I08 rests upon the upper run of a belt 2I9, being held in by set screws 233. The front wall 225 is vertically adjustable so as to permit only one insole at a time to be fed from the bottom of the stack by the belt. Integral with the front wall, one at one end of the wall and one atthe other, are two 'bosses 235, said bosses having vertical bores to receive respectively vertical rods 231, carried by the casting 45, on which the bosses are vertically slidable. Compression springs 238 urge the bosses upward at all times, and nuts 239 threaded on the upper ends of the rods provide means for adjusting the front wall 225 up and down. The feeding belt 219 passes around two rolls 24!, 243 the bearings of which are slidably mounted in the casting 45, adjusting screws 245 being provided for adjusting the bearings of the two rolls to maintain a proper tension on the belt. The middle of the upper run of the belt is supported by an idle roll 241 to prevent sagging of the upper run due to the weight of the stack of insoles.

The insoles, after the grain has been removed from them, pass over a plate 249 and are stacked in a receptacle. Both the plate 249 and the receptacle are supported on two horizontal rods 25!, 253 which are carried by the frame of the machine. The plate 249 (Fig. 2) has a boss at one end provided with a bore through which the rod 25! passes, the boss being provided with a set screw 255. Near the middle of the other end of the plate 24! is an extension which rests upon the rod 253. The plate may thus be adjusted along the rods and held in adjusted position. The receptacle is supported on a base in the form of an inclined plate 251 (Figs. 2, 3) rigidly fastened by screws 259 to the lower substantially horizontal portion of a generally right-angled casting 26!, the upper end of the vertical arm of which has a boss provided with a bore to receive the rod 253. 'The boss on the casting 26! has an enlar ed right-hand end (Fig. 2) which is fastened by screw bolts 263 to a cross-bar 265 which has boresin its opposite ends to receive respectively the rods 253, 25! and is bent downward so asto extend beneath the plate 249 at a distance therefrom. The casting 26!, which supports the receptacle in which the insoles are stacked, may thus be slid along the rods 25!, 253 and will remain in any position into which it is moved. Adjustably fastened to the base plate 251 by screws 261 are two angle irons 269, the screws passing through slots in the horizontal arms of these angle irons and being threaded into the base; and to the upright arms of these angle irons is fastened a guide-plate 21! which serves to guide the insoles into the receptacle. The receptacle itself comprises a side wall 213, an end wall 215 and a bottom 211 which are integral with one another. The'receptacle is normally upright as shown in position to receive insoles, but it may be swung down about the axis of a small rod 219 to facilitate removal of a stack of insoles which have been operated upon. This rod passes loosely through bores in two blocks 28!, Which are in turn fastened to the wall 213 of the'receptacle, and through bores in two other blocks 283 which are adjustably fastened to the base 251 by screws 285, said screws passing through slots in portions of these blocks, and being threaded into the base. The rod 219 is held in place by cotter pins, one of which is shown at 286 in Fig. 1. It is thus possible to adjust the receptacle crosswise of the base 251 and to swing it down about the axis of the rod 219 so as to facilitate the grasping of a stack of finished insoles and the removing of the stack from the receptacle.

The machine is driven from a motor 281 (Fig. l) by means of a belt 289 which passes around a pulley on the motor shaft and around a pulley 29f ona countershaft. A second belt 293 runs around a pulley 295 on the countershaft and around a pulley 291 on the feed roll shaft I82; and a third belt 299, which is crossed, runs around a pulley 30! also on the feed roll shaft and around a pulley 3G3 fast to a shaft 355 which carries the roll 24!, the direction of travel of these belts being indicated by the arrows in Fig. 1.

In the operation of the machine the insoles or other pieces of work are fed one by one from the bottom of the stack in the magazine, pass over the table or work support 9 to the rubber roll and the knife, and thence over the plate 249 into stacked relation in the receptacle.

It should be noted (Fig. 3) that the feeding belt 2!9 is substantially as wide as the knife, that both these members are wider than the insoles which are being operated upon, and that the side walls 22!, 223 are both adjustable across the belt 2!9. With this construction it is possible to adjust the two walls 22!, 223 in the same direction across the belt and thus to direct the insoles to a selected locality on the cutting edge of the knife. Thus, if a locality on the edge of the knife becomes dull from continued use or becomes nicked, the insoles may be fed to another locality.

Although the invention has been set forth as embodied in an illustrated machine, it should be understood that the invention is not limited in the scope of its application to the particular machine which has been shown and described.
